Add hashtags support to WordTwitBudući da sam pokrenuo ovaj blog sam bio koristeći WordTwit by BraveNewCode (oni ponestalo prostora naoko). To je jednostavan za korištenje čep za Wordpress da će se ažurirati svoje Twitter status kad god objaviti novi članak bloga.

Možete prilagoditi svoju poruku i korištenje [naslov] zamijeniti ga s stvarni naziv članka i [veza] s (skratiti) URL na članak. Na taj način te mogao napraviti nešto slično “Novi blog entry ‘[naslov]‘ Posted at [veza]“ – Pa, možda bih ga želite zadržati što je moguće kraća da, ali da bi vam dali ideju.

Dakle s obzirom da možete prilagoditi svoju poruku, također možete dodati jedan ili dva hashtags. Ali to su sve učinio ručno, Na primjer “Blog [naslov] – [veza] # Blog” je ono što sam ja osobno koristeći.

Ali # Blog hashtag zapravo i nije nešto puno ljudi će se tražiti. Pa zašto ne ponovno korištenje oznake koje sam već dodao u moj rad sa Wordpress? Kao što je ovaj članak na primjer, ne mogu koristiti svoje customization oznake kao # customization hashtag u mom cvrkut ažuriranja? Pa, with some modifications to WordTwit, to je moguće. Evo kako.

The modification involves editing the file wordtwit.php, which can be found in your /wp-content/plugin/wordtwit/ imenik. The first part is very minor and simply involves moving a line of code a little further up. You need to look for $post_tags = get_the_tags();” near line 484 (in version 2.2.4 of WordTwit):

...(snip)...
        $can_tweet = true;

        // check tags
        if ( count( $wt_tags ) ) {

            // we have a tag or a category
            $new_taxonomy = array();

            $post_tags = get_the_tags();
            if ( $post_tags ) {
                foreach ( $post_tags as $some_tag ) {
                    $new_taxonomy[] = strtolower( $some_tag->name );
                }
            }
...(snip)...

Move the  $post_tags = get_the_tags();” line up and place it under the $can_tweet = true;” linija. This is done to avoid calling the same function twice. Admittedly, it’s a minor speed hurdle, but if you get into this habit of doing this throughout code, it’ll eventually speed things up. So now the above code will look like this:

...(snip)...
        $can_tweet = true;
        $post_tags = get_the_tags(); // <-- The line was moved here

        // check tags
        if ( count( $wt_tags ) ) {

            // we have a tag or a category
            $new_taxonomy = array();               

            if ( $post_tags ) {
                foreach ( $post_tags as $some_tag ) {
                    $new_taxonomy[] = strtolower( $some_tag->name );
                }
            }
...(snip)...

Up for the next bit.  At around line 515 of the same file (wordtwit.php) you need to inject the code that will handle the WordPress tags to Twitter hashtag conversion. The actual line number will depend on the version of WordTwit you’re using (U ovom primjeru, Verzija 2.2.4) so I have included a snippet of the existing code as a reference where to add it. The actual code will be commented accordingly:

...(snip)...
            $message = $settings['message'];
            $message = str_replace( '[title]', $post->post_title, $message );

            global $post;
            $message = str_replace( '[link]', wordtwit_make_tinyurl( get_permalink(), true, $post->ID ), $message );

// !!! Wordpress tag to Twitter hashtag conversion STARTS HERE >>>

            if ( $post_tags && strpos($message, '[tags]') !== false ) {
                $tags_to_add = '';

                // What's the message length without this tag?
                $message_len = strlen($message) - 6;

                foreach ( $post_tags as $some_tag ) {
                    $tag_len = strlen($some_tag->name) + 2;

                    // Can we add this tag within the 140 char constraint? (accounts for hashtag and spacer)
                    if ( $tag_len + $message_len <= 140 ) {
                        $tags_to_add .= '#'.$some_tag->name.' ';
                        $message_len += $tag_len;
                    } else {
                        // Nope, we're done
                        break;
                    }
                }

                $tags_to_add = rtrim($tags_to_add);
                $message = str_replace('[tags]', $tags_to_add, $message);
            }

// <<< Wordpress tag to Twitter hashtag conversion ENDS HERE !!!   

            $twit_username = $settings['username'];
            $twit_password = $settings['password'];

            twit_update_status( $twit_username, $twit_password, $message );
...(snip)...

Save the file and you’re done with the modification!

Now you can customize your WordTwit message with three replaceable  tags: [naslov], [veza] and the new one [Tags]. When you specify [Tags] in your custom message, WordTwit will use the tags you’re using from WordPress and convert them to a Twitter hashtag. It will try to fit in as many as possible, up to a limit of 140 characters. If you have 10 WordPress tags but there’s only room for 3, then only the first 3 hashtags will appear in your Twitter status update. And obviously all 10 will appear if there’s room for them.
